Tampon and method for making the same

Abstract

An absorbent tampon is disclosed herein. The absorbent tampon has a fiber integrated primary absorbent member having an insertion end and a withdrawal end disposed opposite the insertion end, a top portion and a bottom portion as determined by the Secondary Desorption Performance method, and a secondary absorbent member attached to the primary absorbent member and extending outboard of the withdrawal end of the primary absorbent member. The tampon exhibits a wet weight percentage fluid in the bottom portion of at least about 60 percent when measured in accordance with the Secondary Desorption Performance method.

What is claimed is: 
     
       1. An absorbent tampon comprising:
 a primary absorbent member having an insertion end and a withdrawal end disposed opposite the insertion end, a top adjacent the insertion end, a bottom adjacent the withdrawal end, and a middle disposed between the top and the bottom, the primary absorbent member comprising at least two layers of fibrous absorbent material, the primary absorbent member and/or the at least two layers thereof having a Z-direction fiber integration reflecting, as measured by a Z-Cluster Measurement Test Method as described herein, either or both of: 
 an area of a third largest Z-cluster of greater than 0.01 mm{circumflex over ( )}2; and 
 an average area of a top three clusters of at least 0.02 mm{circumflex over ( )}2; and 
 a secondary absorbent member attached to the primary absorbent member and extending outboard of the withdrawal end of the primary absorbent member. 
 
     
     
       2. The absorbent tampon of  claim 1 , wherein the primary absorbent member comprises between about 50 percent to about 100 percent trilobal rayon fibers and between 0 percent and 50 percent round rayon fibers. 
     
     
       3. The absorbent tampon of  claim 2 , wherein the trilobal rayon fibers have a decitex of between 3.0 and about 4.5. 
     
     
       4. The absorbent tampon of  claim 1 , wherein the primary absorbent member has a basis weight of between about 200 gsm to about 1200 gsm. 
     
     
       5. The absorbent tampon of  claim 4 , wherein the primary absorbent member comprises more than two layers of absorbent material. 
     
     
       6. The absorbent tampon of  claim 5 , wherein each of the layers of absorbent material is spunlaced. 
     
     
       7. The absorbent tampon of  claim 1 , wherein the primary absorbent member exhibits an area of the third largest cluster of greater than 0.03 mm{circumflex over ( )}2. 
     
     
       8. The absorbent tampon of  claim 1 , wherein the primary absorbent member exhibits an average area of the top three clusters of at least 0.03 mm{circumflex over ( )}2. 
     
     
       9. The absorbent tampon of  claim 1 , wherein the tampon exhibits a wet weight percentage fluid in the bottom portion of greater than 60 percent when measured in accordance with a Secondary Desorption Performance method disclosed herein. 
     
     
       10. The absorbent tampon of  claim 1 , wherein the tampon exhibits a wet weight percentage fluid in the bottom portion of greater than 63 percent when measured in accordance with a Secondary Desorption Performance method disclosed herein. 
     
     
       11. The absorbent tampon of  claim 1 , wherein the primary absorbent member comprises 100 percent cotton fibers. 
     
     
       12. The absorbent tampon of  claim 1 , wherein the primary absorbent member comprises a cotton/rayon blend wherein the cotton is present at less than 100 percent. 
     
     
       13. The absorbent tampon of  claim 12 , wherein the cotton is present in an amount of less than about 76 percent. 
     
     
       14. The absorbent tampon of  claim 12 , wherein the cotton is present in an amount of less than about 51 percent. 
     
     
       15. The absorbent tampon of  claim 12 , wherein the cotton is present in an amount of less than about 26 percent. 
     
     
       16. An absorbent tampon comprising:
 a primary absorbent member having an insertion end and a withdrawal end disposed opposite the insertion end, a top adjacent the insertion end, a bottom adjacent the withdrawal end, and a middle disposed between the top and the bottom, the primary absorbent member comprising at least two layers of fibrous absorbent material, the primary absorbent member and/or the at least two layers thereof having been spunlaced to an extent sufficient to impart the primary absorbent member with a Z-direction fiber integration reflecting, as measured by a Z-Cluster Measurement Test Method as described herein, either or both of: 
 an area of a third largest Z-cluster of greater than 0.01 mm{circumflex over ( )}2; and 
 an average area of a top three clusters of at least 0.02 mm{circumflex over ( )}2; and 
 a secondary absorbent member attached to the primary absorbent member and extending outboard of the withdrawal end of the primary absorbent member. 
 
     
     
       17. The absorbent tampon of  claim 16 , wherein the primary absorbent member comprises between about 50 percent to about 100 percent trilobal rayon fibers and between 0 percent and 50 percent round rayon fibers. 
     
     
       18. The absorbent tampon of  claim 17 , wherein the trilobal rayon fibers have a decitex of between 3.0 and about 4.5. 
     
     
       19. The absorbent tampon of  claim 16 , wherein the primary absorbent member has a basis weight of between about 200 gsm to about 1200 gsm.
